To all 1072.011?, it may concern: ranged to engage the notches of the sector. Be it known that I, MARSHALL N. KIRK- Above arm 16 the guide-plate is formed into HUFF, of the city of Canton, county of Fulton, or provided with a notched sector 10. A lever and State of Illinois, have invented certain 11 is pivoted to the guide-plate at point 12, 55 new and useful Improvements in l/VheeL which point is concentric with the arc of sec'- Plows, of which the following isa speciticator 10, and a spring-bolt 13 on lever 1l is tion. adapted to engage the notches of sector 10. Theinvention relates to mechanism for con- An arm 23 extends backward from lever 1l, trolling the side furrow-wheelofwheel-plows; forming therewith a bell-crank lever, and a 6o 1o and it provides means for raising and lowerlink 24 connects the extended end of the arm ing the wheel with relation to the frame, or with the slide 4.

Fig. 2 is slide 4 through arm 23 and link 24 is used to an elevation showing the inner side of the raise and lower the wheel with relation to the 75 controlling mechanism. Fig. 3 is an elevaplow-frame or to raise and Ylower the frame tion of the outer side of the controlling niechwith relation to the wheel, according to the anisin, showing the spindle of the wheel set View taken of the operation. The wheel rests to give the wheel a lead toward the vertical on the ground,-and the lever lifts the weight wall of the furrow. Fig. 4 is a detail plan of of that part of the plow-frame adjacent to 8o 3o the wheel and the slide therefor. Fig. 5 is a the wheel by pushing down on the wheel, and

At 2 is shown the through hand-lever 19, the guide-plate and wheel-spindle, which is inclined downward the lever 11 constitute a continuons lever and outward. The spindlebracket is shown whereby the spindle ot' the wheel is rocked on at 3, and at 4 is shown a slide, with which the pivot 9, as shown in Fig. 3. When it is despindle-bracket connects rigidly. The aXlesired to give the wheel lead toward the fur- 9o 4o bar 5 extends sidewise from a plow-frame of row-line, which is marked F L in the drawany suitable construction, and to its end ings, the spindle is swung forward, as shown brackets Gand 7 are rigidly secured.

The upper extension of bracket 7 in Fig. 5. In Fig. 4 the spindle is pointed is formed into a notched sector the arc of directly outward, and so the wheel tends to which is concentric with the pivot 9 of the run parallel with the furrow.

An arm 16 is pivoted on the The lead of the wheel to or from the furroo 5o guide-plate above the sector of bracket 7, and row may be regulated by setting the bolt 17 a spring-bolt 17 is pivoted on the arm and arin different notches of the sector on bracket 7, and the vertical position of the wheel with relation to the frame may be varied by setting!` bolt 13 in dierent notches of sector 10.

The lead of the wheel to and from the furrow-wall facilitates the guiding of the plow, and the adjustment of the wheel Vwith relation to the frame enables the frame to maintain a horizontal or a position parallel with the general lay of the ground under all conditions.

I claim- 1. In a wheel-plow, the combination with a frame, of a plate pivoted to swing vertically forward and back on a side of the frame, a spindle extending outward and downward from the swinging plate, a wheel mounted on the spindle, and a lock-lever to control the swing of the plate.

2. In a wheel-plow, the combination with a frame, of a guide-plate pivoted to swing vertically forward and back on a side of the frame, a slide mounted on the plate, a spindle extending downward and outward from the slide, a wheel on the spindle, means for raising and lowering the slide on the guideplate and a lock-lever to control the swing of the guide-plate.

.3. In a wheel-plow, the combination with a frame, ofl a 'guide-plate pivoted -to swing vertically forward and back on a side of the frame, a slide mounted on the guide-plate, a spindle extending downward and outward from the slide, a wheel on the spindle, a notched sector xed on the frame adjacent to the guidesplate, a lock-bolt on the guideplate to engage the notches of the iixed sector, a notched sector on the upper end of the guide-plate, a lever pivoted on the plate, a lock-bolt on the lever to engage the notches of the sector on the plate, a connection between the lever and the slide whereby swing ofthe lever will raise and lower the slide, and means on the lever for disengaging the lock-bolts from their sectors.

4E. In a wheel-plow, the combination with a frame, of a guide-plate pivoted to swing vertically forward and back on a side of the frame, a slide mounted on the guide-plate, a spindle extending downward and outward from the slide, a wheel on the spindle, a notched sector fixed on4the frame adjacent to the guide-plate, a lock-bolt on the guideplate to engage the notches of the xed sector, a notched sector on the upper end of the guide-plate, a lever pivoted on the guideplate, a lock-bolt on the lever to engage the notches of the sector on the plate, an arm on the lever, a link connecting the arm with the slide, a finger-lever ou the main lever connected with the lock on the guide-plate and a second finger-lever on the main lever connected with the bolt on the main lever.

In testimony whereoi` I sign my name in the presence of two subscribing witnesses.
